Roulette is a casino game which was invented in France where a ball is span around the mouth of a bowl at the base of which is a spinning wheel with divisions numbered 0-36. The numbers are coloured red or black and include a green 0. An American wheel gives more of an edge to the house by having an additional green 00. The numbers have a particular order where a red 32 is to the right of the 0 and a black 26 to the left. A croupier will spin the wheel, and roll the ball in the opposite direction. When the ball drops it may hit a diamond these are metal ridges between the mouth and the base which deﬂect the ball. They disrupt the trajectory of the ball and make it more diﬃcult to predict its landing.
Bets are only permitted before the ball is spun. Bets are made on a betting mat where the placement of the chip indicates where you think the ball will land. The mat is split into diﬀerent markets including the green which weighs favour towards the house. Markets which appear to be 50/50 are aﬀected by that green 0. Traditionally mats have French term for the markets printed, even in English speaking countries so we have included them also.

Odd/Impair - The ball will land on an odd number
Red/Rouge - The ball will land on a red number
Black/Noir - The ball will land on a black number

First dozen/Premiere douzaine/1-12 - The ball will land on a number between one and 12
Middle dozen/Moyenne douzaine/13-24 - The ball will land on a number between 13 and 24
Last dozen/Dernier douzaine/25-36 - The ball will land on a number between 25 and 36
Column/Colonne - A column of 12 numbers as laid out on the mat
Line bet/Sixain - Bet on six numbers by putting a chip at the intersection of two rows - Payout: 5-1 Odds: 16.2%

When the ball comes to a stop in one of the slots the croupier will announce the result collect up the losing bets and hand out winnings.
Odds in Roulette are always slightly weighted in the house’s favour. In European the house edge is 2.7% and on an American wheel the house has an advantage of 5.26%. This is caused by the green 0 which when landed on voids all bets. Working out your odds on the ﬂy can be diﬃcult as it requires by dividing 36 by the total number of squares your bet covers. For your payout subtract one. To save you the hassle though we have a quick guide below:

The martingale method of betting on roulette encourages you to double your bet after a loss. If you lose a £5 bet then your next bet will £10 meaning if you win will have made up your £5 loss and be up £5. This can result is heavy losses as you are doubling your bet every time you lose so it only takes four losses before you are betting triple ﬁgures.
The ﬁbonacci sequence is a mathematical phenomenon in which the next number in a sequence is determined by adding together the previous two. 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144… You can use this sequence to decide how much you bet in each round. Let’s say the ﬁrst bet is £5, you lose and you bet £5 again. This bet loses and this time you bet £5 + £5 so £10. If this one loses you will bet £5 + £10 so £15. You continue doing this each time you place a losing bet.
As Jeﬀ Goldblum brieﬂy explains to us in Jurassic Park, small changes in a complex system can have devastating unpredictable eﬀects. Roulette chaosticians believe you should not think about your bets because it is impossible to predict events. Therefore you should place your bets with reckless abandon, in no particular order or amount.
Some houses have a policy where they only take half your bet and return the other half on 1-1 bets when the ball lands on 0. This reduces the house edge in half and any system which reduces the edge is the best one in our books. This is not a common policy but at a house which operates this, get betting on that wheel!
Lightning roulette follows the same rules and layout as European roulette however for each spin up to ﬁve numbers can be hit with a multiplier. The multipliers range from between 50x and 500x, they are only applied to single numbers and are not applied until all bets have been placed. If you win a single number which has multiplier placed on it your winnings are multiplied by that amount. This means the payout on a single number without a multiplier is reduced to 29-1.
You will not get multipliers applied to grouped bets so remember if you want to win big then you need to place only straight numbers bets. There is no use in looking at previous numbers which have placed and multiplied because for lightning roulette to truly be fair these must be assigned randomly. As there are no multipliers on grouped bets the only way to reliably hit a multiplier is to bet on all straight numbers or every other number. With returns reduced to only 29-1 there will be some losses every time so you are relying on hitting a multiplier pretty early on.
